"""Saejae-1 P1 column rebar reading (G2: P1~P5) -> 판독/g2_values.json.

Sheet 구조도(1) front view: column CL x 225532, z = drawing y - 10329.7 (footing bottom y 20361.7 = EL 10.032, top y 22961.7).
The column is drawn broken (cut symbol), so only 42 hoop lines are drawn; the dimension chains give all levels:
'띠철근외측' 100 | 1.300 | 4@300 | 18@150 | 36@300 | 9@300 | 4@300 | 2.375 | 125 (= 22.500 from the footing bottom, 72 hoops),
'크로스타이' 100 | 950 | 600 | 7@300 | 15@600 | 14@300 | 2@600 | 4.225 | 125 (= 22.500, 40 levels).
Sheet 구조도(2) sections: bar symbols on r 975 (P1, 49) and 930 (P2, 49), hoop arcs r 997.5, ties through the centre.
